16 FEB 2026 · In this episode of SpaceTime, we delve into groundbreaking revelations regarding the Earth's core, solar neutrinos, and the volcanic activity on Mars.
Earth's Core Contains Oceans of Hydrogen
A recent study published in Nature Communications reveals that the Earth's core may hold up to 45 oceans worth of hydrogen. This finding challenges the long-held belief that Earth's water primarily came from asteroids and comets. Using advanced laboratory techniques, scientists simulated the extreme conditions of the core and discovered significant levels of hydrogen, suggesting a more complex history of water on our planet.
Neutrinos from the Sun's Core
In a significant breakthrough, the LUX-ZEPLIN experiment has detected neutrinos originating from the core of the Sun, marking a milestone in our understanding of these elusive particles. This discovery not only sheds light on solar processes but also enhances the search for dark matter, as the interactions observed mimic those expected from dark matter particles.
Volcanoes on Mars: A Complex History
New research published in Geology indicates that Mars' young volcanoes are far more intricate than previously thought. Rather than forming from single eruptions, these volcanoes were shaped by long-lasting and evolving magma systems. This study provides insight into the Red Planet's volcanic activity, revealing a dynamic history of eruptions and magma evolution.

16 FEB 2026 · In this episode of SpaceTime, we delve into groundbreaking revelations regarding the Earth's core, solar neutrinos, and the volcanic activity on Mars.
Earth's Core Contains Oceans of Hydrogen
A recent study published in Nature Communications reveals that the Earth's core may hold up to 45 oceans worth of hydrogen. This finding challenges the long-held belief that Earth's water primarily came from asteroids and comets. Using advanced laboratory techniques, scientists simulated the extreme conditions of the core and discovered significant levels of hydrogen, suggesting a more complex history of water on our planet.
Neutrinos from the Sun's Core
In a significant breakthrough, the LUX-ZEPLIN experiment has detected neutrinos originating from the core of the Sun, marking a milestone in our understanding of these elusive particles. This discovery not only sheds light on solar processes but also enhances the search for dark matter, as the interactions observed mimic those expected from dark matter particles.
Volcanoes on Mars: A Complex History
New research published in Geology indicates that Mars' young volcanoes are far more intricate than previously thought. Rather than forming from single eruptions, these volcanoes were shaped by long-lasting and evolving magma systems. This study provides insight into the Red Planet's volcanic activity, revealing a dynamic history of eruptions and magma evolution.
